„Extreme Internet use among young people is common in OECD countries. On average, 24 % of 15-year-olds spend more than 6 hours a day on the Internet on weekend days, and a figure that is as high as 43 % in Chile and 37 % in the United Kingdom. Culture may play a role in the extent to which children spend long periods of time online, with the lowest share of extreme users among children in Japan and Korea. The level of educational achievement of parents also seem to be associated with extreme Internet use, with children of highly educated parents less likely to be extreme Internet users in most countries.“
